Abstract:ABSTRACT. The purpose of this paper is to construct the asymptotic for natural frequencies of the Schrödinger equation using the method of Wentzel-Kramers-Brillouin (WKB).
“…It was constructed the asymptotic for natural frequencies of the Schrödinger equation using the (WKB) method [4]. It was encountered a formula explicitly to the eigenvalue that appears below the essential spectrum of the discrete equation Klein-Gordon [3].…”
In this paper we construct a resonance of the discrete Schrödinger equation in presence of a potential. To achieve this, we use Whittaker-Kotelnikov interpolation, Fourier transform and Neumann series.
